Kilopounds per square inch to Gigapascals converter

To convert kilopounds per square inch to gigapascals, enter the value in the first field. The result in gigapascals is calculated automatically using the exact conversion factor.

1 ksi ≈ 0.00689475729317 GPa
1 GPa ≈ 145.03773773 ksi

Formula: GPa ≈ ksi × 0.00689475729317
ksi ≈ GPa × 145.03773773

Definitions: 1 ksi = 1000 psi; 1 GPa = 1000000000 Pa

The kilopound per square inch (ksi) is 1,000 psi. It is used in United States structural and materials engineering for the strength of steel and concrete, for example steel with a yield strength of 36 or 50 ksi.

The gigapascal (GPa) is one billion pascals. It is used for very high stresses and for stiffness (Young's modulus), where steel is about 200 GPa, and for pressures deep inside the Earth.
